A mixture of 4-benzylsulfanyl-benzaldehyde (840 mg 3.68 mmol) described in Manufacturing Example 205-1-2, nitromethane (997 μL, 18.4 mmol), ammonium acetate (567 mg, 7.36 mmol), and acetic acid (10 mL) was stirred for 2 hours at 100° C. This mixture was cooled to room temperature and concentrated under reduced pressure. The residue was partitioned into ethyl acetate and water. The organic layer was separated, washed with water and saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (950 mg). The title compound was used in the following reaction without any further purification.
